Wireless stimulation device

Abstract

The invention discloses a wireless stimulation device. The wireless stimulation device comprises a wireless energy generator and a passive implant, wherein the wireless energy generator comprises a host and a transmitting coil connected with the host; the passive implant comprises a receiving coil and an electrode connected with the receiving coil; the host comprises a control panel, an external communication interface, a power supply module, a main control chip, a signal generator, a power adjusting module and a frequency adjusting module; and the control panel comprises a touch screen, a power button and an adjusting knob, so that the host can set the stimulation frequency, the pulse width, the voltage magnitude and the stimulation time in a user-defined manner. The electrode and the receiving coil are integrated, and power is supplied through external electromagnetic coupling, so that the implant is smaller in size and lighter in weight, implantation injuries and postoperative discomfort are reduced, in-vitro wireless power supply is not limited by the service life of a battery, continuous and long-time stimulation can be achieved, and animals moving freely can be stimulated ina certain space.

Description

technical field [0001] The invention relates to an animal stimulation device, in particular to a wireless stimulation device. Background technique [0002] The most common animal stimulation system on the market in the early days used wired connections. The stimulating electrodes were implanted in the animal body and then the wires were plugged in. The external equipment was adjusted to stimulate the required parameters. However, this wired technology limited the range of animal activities, and the wire The weight of the animal will also affect the normal behavior and comfort of the animal, affecting the experimental results. In recent years, with the rise of microelectronic processing technology, a wireless stimulation mode has gradually appeared, integrating the stimulation electrodes and stimulation equipment, and miniaturized design, but this part of the mode is powered by batteries, and the weight of the battery accounts for a relatively large proportion of the weight o...

[0002] The most common animal stimulation system on the market in the early days used wired connections. The stimulating electrodes were implanted in the animal body and then the wires were plugged in. The external equipment was adjusted to stimulate the required parameters. However, this wired technology limited the range of animal activities, and the wire The weight of the animal will also affect the normal behavior and comfort of the animal, affecting the experimental results

In recent years, with the rise of microelectronic processing technology, a wireless stimulation mode has gradually appeared, integrating the stimulation electrodes and stimulation equipment, and miniaturized design, but this part of the mode is powered by batteries, and the weight of the battery accounts for a relatively large proportion of the weight of the implant. High, and the volume is still not suitable for small animals (big, mice, etc.) after being compressed to a minimum, and this implant cannot continue to work after the energy of the battery is exhausted, and cannot be used for those long-term stimulation experiments.
